A columnar cooling tube bundle with a wedge-shaped gap, including two finned tube bundles, which intersect at one side with a set angle and open at the other and form a wedge-shaped gap; with the intersection as an origin, a distance l extends to the opening side, the bundles share fins within 0-l, wherein l is no more than half the distance between the two sides. When air inflows vertically to the louver of the cooling unit, fresh air is directly introduced into the cooling tube bundle to improve the average heat transfer temperature difference of the cooling tube bundle and intensify the heat transfer; when air inflows obliquely, it impacts the inner space of the cooling unit, therefore the low-speed eddy area is reduced, both the cooling performance of the tube bundle and cooling unit overall is improved, and the cooling performance of the dry cooling tower is improved. 1. A columnar cooling tube bundle with a wedge-shaped gap , comprising two finned tube bundles , which intersect with each other at one side with a set included angle and open at the other side , and then form a wedge-shaped gap between the two finned tube bundles.2. The columnar cooling tube bundle with the wedge-shaped gap of claim 1 , wherein the two finned tube bundles are symmetrically arranged.3. The columnar cooling tube bundle with the wedge-shaped gap of claim 1 , wherein when the two finned tube bundles are vertically arranged claim 1 , one of the two finned tube bundles is the upstream side tube bundle claim 1 , and the other of the two finned tube bundles is the downstream side tube bundle.4. The columnar cooling tube bundle with the wedge-shaped gap of claim 1 , wherein when the two finned tube bundles are horizontally arranged claim 1 , one of the two finned tube bundles is the first single-pass tube bundle claim 1 , and the other of the two finned tube bundles is the second single-pass tube bundle.5. The columnar cooling tube bundle with the wedge-shaped gap of claim 1 , wherein the ...
